Step 301, the planning system sends a scheduling request to each industrial site;

In step 301, when an enterprise needs to arrange a planning and scheduling task, it sends a scheduling request to the enterprise's industrial site through the planning system; further, the planning system calculates the purchase demand of each industrial cooperation site and sends this purchase information to the directly connected complete site; the industrial site within the enterprise sends the purchase demand information to the indirectly connected complete site; the directly connected complete site and the indirectly connected complete site are both industrial sites of the supplier; the planning system is a system for planning and scheduling work tasks for the enterprise;

Step 302, determine whether the site receiving the information is an industrial cooperation site; if yes, proceed to 303; if no, proceed to 305;

Step 303: After receiving the purchase information, the supply chain industry cooperation site performs a plan scheduling operation within the enterprise, verifies the feasibility of the plan, and obtains the revised purchase demand information;

Step 304, the supply chain industry cooperation site feeds back the revised procurement information to the procurement demander;

In step 304, the directly connected full site directly feeds back the revised purchase information to the planning system of the purchase demand side; the indirect connected full site and the interactive site feed back the revised purchase demand information to the industry site of the purchase demand side, and then the industry site feeds back the revised purchase demand information to the enterprise planning system;

Step 305, the planning system performs scheduling operations with the industrial sites, the directly connected complete sites, and the indirectly connected complete sites to form distributed operations;

In step 305, the industry sites, directly connected full sites, and non-directly connected full sites directly participate in the planning and scheduling calculation, and together with the enterprise planning system server, form a distributed computing network; the interactive sites wait for the scheduling results; the directly connected full sites, non-directly connected full sites, and interactive sites are all industry sites of the supplier;

Step 306, determine whether an industrial cooperation site verification plan is needed; if yes, proceed to step 303; if no, proceed to step 307;

Step 307, determine whether the plan has been modified; if yes, return to step 301; if no, proceed to step 308;

Step 308, confirming the scheduling calculation result, the purchaser sends a purchase authorization code to the supplier, and the supplier sends a supply authorization code to the purchaser, and after both parties receive the authorization code, they enter the execution plan stage;

In step 308, the purchaser is composed of a planning system and an industry site, and the supplier is composed of a direct-connected complete site, an indirect-connected complete site, and an interactive site;

After confirming the scheduling calculation results, the planning system sends the purchase authorization code to the directly connected full site, and the industrial site sends the purchase authorization code to the non-directly connected full site and interactive site;

The directly connected full site sends the supply authorization code to the planning system, and the indirect connected full site and interactive site send the supply authorization code to the industrial site;

After receiving the authorization code from each other, the execution plan phase begins.

4. The supply chain collaborative planning and data sharing method according to claim 3 is characterized in that:

The specific steps of the execution plan stage include:

Step 401, all sites enter the plan execution process;

Step 402: An industry site or an industry cooperation site receives an abnormal signal; the industry cooperation site includes a directly connected complete site, an indirect connected complete site, and an interactive site; the abnormal signal is any abnormal situation encountered by the industry cooperation site during the execution of the plan;

Step 403, determine whether the site is an industrial cooperation site; if yes, proceed to step 404; if no, proceed to step 406;

Step 404, the industrial cooperation site feeds back to the planning system of the enterprise, and further performs the scheduling operation of the enterprise first;

The enterprise in step 404 is the enterprise to which the industrial cooperation site belongs and is also the supplier of the supply chain. The purpose of executing the scheduling operation of the enterprise first is to verify the feasibility of the plan.

Step 405, judging whether it is necessary to trigger the purchaser's plan and schedule according to the plan and schedule result; if yes, proceed to step 407; if no, proceed to step 401;

In step 407, the planning system performs scheduling calculation again; that is, enters step 301.
